The algorithm indicates the position of a radiological signs in a digital volume by means of markers. The algorithm has the potential to distinguish automatically between malignant elements and benign elements. The algorithm comprises a fuzzy logic approach to explain the ambiguities in the image. The algorithm is applied directly to the radiography projection images.

    摘要: In a method for the processing of radiology images for detection of radiological signs, an algorithm is provided to detect such radiological signs on projections as a function of their contrasts. These contrasts are measured by using the responses of linear differential filters with different scale parameters. The method can be used to color or enhance the intensity of the radiological signs detected as a function of their degree of malignancy. The algorithm may be applied directly to the signal given by the detector.

    摘要: A method of image processing in a radiological apparatus includes reconstructing a 3D image of a body from a set of radiography projection images, locating structures presumed to be representative of 3D radiological signs within the 3D image, determining a set of 2D candidate particles corresponding to projections of the presumed 3D radiological signs, assigning, through a fuzzy logic description, to the 2D candidate particles a degree of membership in 2D membership classes of a set of membership classes, each membership class being relative to a type of radiological sign, considering a 2D fuzzy particle being formed by the set of the 2D candidate particles and by their respective degrees of membership in a class, making an aggregate of the 2D fuzzy particles to obtain 3D fuzzy particles in a digital volume, and determining a degree of confidence for each 3D radiological sign from the 3D fuzzy particles.
